Air Conditioning for Data Center

In regards to the air conditioning for IT data center, I would like to hear how to solve the following posible problem. I designed a tipical chilled water CRAC, hot and cold aisle configuration, and it works well. The problem is when the general power is off and due the timing before the generator stars, chillers goes off. When generators start working, the chillers take aprox 10 minutes to get the full running. So, my worry is what happen with the temperature in the room. I did some calculation and due to the equipment load inside the room it is possible to reach 32ªC in about 3 minutes. Is any way to back up this lack of chilled water by an inertia chilled water tank or something like that. Probably some body has already solve this problem somehow and might hepl me.
Thanks in advance

Regards

Since my uncle is working in a air-conditioning indianapolis company, perhaps I could ask him about this issue and i could also ask him for some information about it.

Or you could outfit your DC with a battery Room UPS to bypass the time that the generators need to start up.
This is a common practice within DC's.

It isn't common practice to back up chillers with UPS. Most use thermal storage tanks... I've seen some use louvers to duct hot air outside while the chiller plant comes back online

Depends on the size of the DC. I've seen it happen allot here in Europe.

But i can see why a big DC will use thermal storage thanks or redirect airflow.
